Yep, I agree, cosmetically beautiful veggies are not required, and as chemicals get cheaper and cheaper, more and more farmers here in Cambodia are choosing chemical farming.
Our neighbor actually owns an excavator, and about 10km from here, I saw an excavator enter the river at low water and move boulders to one side for reinforcement. He said he could do this at the right time of the years, and we've estimated it might cost around $1,000 USD to reinforce the riverbank along our entire property with boulders moved from the opposite side and the middle of the river.
